THE ONE-LINER

flashkube.dev is an arcade game that teaches Kubernetes — a targeted certification prep course wearing an arcade cabinet.

BOILERPLATE

flashkube is a free-to-play flashcard voyage through Kubernetes and its ecosystem: one ocean of nineteen islands, crossed a run at a time, with streaks, lives, chiptune bleeps and weekly leaderboards signed with 3-letter arcade tags. Progress is carried by an inked sea chart and by a written log in the voice of Helm, the helmsman — who never explains the answer. Under it is a spaced-repetition engine that schedules every card, notices what you keep confusing and drags those concepts into head-to-head Showdowns. The paid Cert Cartridge adds exam-mapped cartridges for the CKAD, CKA, CKS, KCNA, KCSA and Data Engineer Professional certifications: readiness soundings cut by official curriculum domain weights, timed mock runs, study plans paced to your exam date, and an in-game coach. The exams are hands-on — flashkube is the recall layer that makes lab hours count.

FAST FACTS

• 🕹 Playable in ten seconds: no-account demo at flashkube.dev/demo
• 🗺 19 islands · 56 landings · 1083 cards · 9 cartridges across 8 archipelagos
• 🎮 One game per cartridge: Pod Wreck, Pod Heading, Cluster Salvage, Namespace Boarding, Cluster Compass, Secret Watch, Delta Rapids, Operator Convoy, Fetch — the game you play depends on how you are examined
• 🃏 8 card types: term recall, multiple choice, name-that-resource, YAML spot-checks, diagram taps on pixel-art diagrams, typed kubectl commands, K9s key routes graded by par, and task chains run against a simulated cluster
• 🧠 Spaced repetition (FSRS, scheduled to your exam date), the daily voyage, confusion-pair Showdowns, soundings
• 💾 Three islands of free water, from wherever you land — the open ocean's first three hold 271 cards; the Cert Cartridge is $29, paid once — no subscription, no renewal, and it stays yours
• 🎨 Everything hand-built: diagrams are in-repo SVG, every sound is synthesized in the browser — no audio files. Helm's plates are commissioned illustration, one per sea.

HOW TO DESCRIBE IT

Accurate: “a study game,” “a recall trainer,” “an arcade-style companion to hands-on prep.” Not accurate: “an exam simulator” or “a lab environment” — the certification exams are hands-on, and flashkube deliberately complements cluster practice rather than replacing it. Every card is original, blueprint-weighted study content written against the public curricula — never exam questions.
